| برای انجام این آزمایش تعداد 450 قطعه نیمچه مادر گوشتی(راس 308)، با 6 تیمار و 5 تکرار و 15 پرنده در هر تکرار در 30 واحد آزمایشی توزیع شدند. آزمایش به‌صورت فاکتوریل 2 × 3 در قالب طرح کاملا تصادفی با 3 شکل خوراک (آردی، کرامبل و پلت) و 2 سطح غلظت مواد مغذی (جیره استاندارد و جیره رقیق‌شده به مقدار 90% استاندارد) در دوره رشد (7 تا 19 هفتگی) و دوره پیش‌تولید (19 هفتگی تا شوک نوری) انجام شد. نتایج نشان داد در دوره رشد شکل خوراک در جیره رقیق‌شده تأثیری بر وزن نیمچه‌ها نداشت. در حالیکه استفاده از خوراک پلت در مقایسه با خوراک آردی در جیره استاندارد سبب افزایش معنی‌دار وزن بدن شد (05/0 P <). در دوره پیش‌تولید استفاده از خوراک‌های پلت و کرامبل در مقایسه با خوراک آردی سبب افزایش معنی‌دار وزن بدن و رقیق‌سازی جیره سبب کاهش معنی‌دار وزن بدن نیمچه‌های مادر شد (05/0 P <). شکل خوراک و غلظت مواد مغذی تأثیر معنی‌دار بر ریخت‌شناسی پرزهای ژژنوم نداشتند (05/0 P >). استفاده از خوراک پلت در مقایسه با خوراک آردی سبب افزایش ضخامت بخش کرانیودورسال ضخیم ماهیچه‌های پشتی سنگدان نیمچه‌ها شد (05/0 P <). بر اساس نتایج این آزمایش، استفاده از جیره پلت یا کرامبل حاوی سطوح مواد مغذی توصیه شده کنترل وزن در گله‌های مادر گوشتی را به دلیل افزایش وزن بیشتر می‌تواند با مشکل مواجه کند ولی رقیق‌سازی جیره به مقدار 90 درصد مقدار مواد مغذی توصیه شده تا حدود زیادی در کنترل وزن موثر است. | ||

| A total of 450 Ross 308 female broiler breeder pullets were distributed into 30 experimental units with 6 treatments and 5 replicates with 15 birds per each. The experiment was performed in a a completely randomized design with a factorial 2 × 3 arrangement consisted of 3 feed forms (mash, crumble, and pellet) and 2 levels of nutrient density (standard diet and diluted diet to 90% standard) in the grower and pre-breeder periods. The results showed that feed form in the diluted diet had no significant effect on the weight of broiler breeder pullets during the grower period, while the use of pellet feed compared to mash feed in the standard diet caused a significant increase in body weight (P< 0.05). Pellet and crumble feeds compared to mash feed in the pre-production period caused a significant increase in body weight and diet dilution caused a significant decrease in the body weight of broiler breeder pullets (P<0.05). Neither feed form nor nutrient density significantly affected jejunum villi morphology (P> 0.05). The use of pellet feed compared to mash feed caused an increase in the thickness of the gizzard dorsal muscles (P< 0.05). Based on the results of this experiment, the use of pellet or crumble diets containing nutrients recommended levels can cause problems in weight control in broiler breeder pullets due to increased weight, but diluting the diet to 90% of the nutrients recommendation are effective to a large extent in controlling body weight. | ||
